Probably only one if just powering the display. Two if cranking. EFI likely doesn't run off the battery.So i’ve tested all the relays. All click with power supplied and show 0 ohm resistance. Replacing them anyways when they come in the mail.
I crossed the solenoid posts and it turns over fine. Still zero life to gauges, efi, etc.
Im thinking kill switch is bad or grounding out somewhere, but i have a question. When the key is turned, how many prongs on the key switch should be sending current? So far as I can tell, only one is on mine.
